Re: [mapserver-users] WFS layer - XML/JSON safe chars

[Rahkonen Jukka (MML)]

Hi Ian,

Thanks for the clarification.
I made a simple test by adding an abstract into layer metadata. This shows 
“test ä” as an abstract
"wfs_abstract" "test ä”

This one shows an empty abstract
"wfs_abstract" "test ä &"

So it looks like Mapserver doesn’t know to convert “&” into “” for XML.

Jukka,

Our question was for the data/text read from the database and then published as 
XML by the WFS service.

So a pub with the name ‘Dog & bone’ created illegal xml as the & is not 
converted to

Hi,

You can’t have & in feature type names or attribute names in WFS because they 
are defined in the XML schema to be “QName”. The prefix and LocalPart are of 
type NCName https://en.wikipedia.org/wiki/QName and from 
http://stackoverflow.com/questions/1631396/what-is-an-xsncname-type-and-when-should-it-be-used

The practical restrictions of NCName are that it cannot contain several symbol 
characters like :, @, $, %, &, /, +, ,, ;, whitespace characters or different 
parenthesis. Furthermore an NCName cannot begin with a number, dot or minus 
character although they can appear later in an NCName.

Aihe: [mapserver-users] WFS layer - XML/JSON safe chars

Folks,

Can mapserver produce XML or JSON safe characters for WFS served data or do we 
need to ensure the source data has the escaped values.

We got tripped up today as there were some ‘&’ in our names which we had not 
considered.

Thanks

Re: [mapserver-users] Symbol size in meters, width in pixels units

[Stephen Woodbridge]

Thomas,

Please take a moment to review this library:

http://www.angusj.com/delphi/clipper.php

I've used the JavaScript version to do offsets in the browser. It could 
be used to offset and linestring or polygon object like a circle and 
IIRC, it also does one sided offsets. It also does lots of other cool 
things like polygon clipping intersection, union, difference, etc.


This might be a handy set of tools for geoprocessing and offsets in 
geometry space.

Re: [mapserver-users] Symbol size in meters, width in pixels units

[Michal Seidl]

Thanks for replay.

Actually I am triyng to size circle vector symbol in map/meters/units. 
It works perfectly till you use only COLOR and not OUTLINECOLOR. All is 
needed is SIZEUNITS meters at LAYER level and then STYLE SIZE is then 
computed not in pixeles but map meters.


Unfortunatelly the OUTLINECOLOR strip is also sized so the result symbol 
size is not correct.

For lines, you have the OUTLINEWIDTH keyword which is always in pixels.

Hi,
I can see the same behaviour with Mapserver 6.4 driver AGG. I am affraid it
is not possible. Unfortunaltely. I din not find any workaround.
